More InfoQuote

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes.

The 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.

Key Features

  • Waveform observation across a wide band from DC to MHz
  • Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
